COMPARISON STUDY OF JOINING Ni-ALLOY WITH GRAPHITE

Modeling of diffusion bonding of Inconel 600 /Pyrolytic Graphite and Inconel 600/steel interlayer/Pyrolytic Graphite is investigated in this research. Modeling implies utilization of ANSYS package to predict axisymmetric thermoelastic finite element analysis from the above materials. The model is used; to calculate thermal stresses induced across diffusion bonded joints. Investigating thermal stress levels along the potential failure interface for both joints is extremely helpful; these residual stresses are mostly the forces of joint failure for both joints. Axisymmetric finite element analysis involves applying temperature along the whole joint as main parameter; the second parameter was changing the steel interlayer.
